Explicit infiltration equations and the Lambert W-function

David Andrew Barry

The Green and Ampt infiltration formula, as well as the Talsma and Parlange formula, are two-parameter equations that are both expressible in terms of Lambert W-functions. These representations are used to derive explicit, simple and accurate approximation ...

Primary-backup replication: From a time-free protocol to a time-based implementation

André Schiper

Fault-tolerant control systems can be built by replicating critical components. However, replication raises the issue of inconsistency. Multiple protocols for ensuring consistency have been described in the literature. PADRE (Protocol for Asymmetric Duplex ...

A strongly nonlinear problem arising in glaciology

Jacques Rappaz

The computation of glacier movements leads to a system of nonlinear partial differential equations. The existence and uniqueness of a weak solution is established by using the calculus of variations. A discretization by the finite element method is done. T ...

A time-domain iterative approach to correct the transmission line approximation for lines of finite length

Michel Ianoz

We present an iterative approach to correct the results obtained using the transmission line (TL) approximation for lines of finite length above a perfectly conducting X ground. The method can be applied both in the frequency- and in the time-domain. The p ...

A class of exact solutions for Richards’ equation

David Andrew Barry

A new solution satisfying Richards' equation is derived. The solution, which may be applied for infiltration or capillary rise, is valid for the condition of an arbitrary moisture tension imposed at the soil surface. When written in terms of the moisture t ...

Mixing cell models for nonlinear nonequilibrium single species adsorption and transport

David Andrew Barry

The oft-used “standard” mixing cell model describing reactive solute transport is extended to cater for nonequilibrium reactions. For tracer transport, the standard model is second-order accurate in the space and time discretization used. However, an error ...

Electrodynamics of a Superconductor Superlattice in the Mixed State

Alexander Tagantsev

We study the electrodynamics of a superconductor superlattice consisting of layers of two kinds (wide layers with extremely weak pinning and very thin layers with-strong pinning), in a perpendicular magnetic field. The problem is treated with the nonlocali ...
